Surviving Sedation Guidelines 2017

20130801-060427.jpgguess-the-emoji-lrg-745sleep

Currency : reviewed and updated with new reference list March 2017

Authorship : Dr Minh Le Cong, Dr Andy Buck, Dr George Douros, Dr Casey Parker, Dr Tim Leeuwenberg,

Peer reviewers: Dr Amit Maini,  Dr Peter Fritz, Dr Michael Downes

Intended target audience for this guideline:

  • The occasional sedationist e.g rural health provider, medical resident on ward
  • Those who encounter acutely agitated patients in low resource settings such as rural clinics/hospitals i.e no formal security team response

Rationale/background to this guideline:  The emergency sedation of the acutely agitated patient is a high risk procedure for both the patient as well as the treating providers. Recurrent cases of sedation related misadventures and deaths have motivated the authors of this document to produce this evidence and practice based consensus guideline. We have coined the title “Surviving Sedation Guidelines” as a paraphrase to the well known “Surviving Sepsis” campaign to draw attention to key principles of safe sedation that we believe to be the pillars of quality care and patient safety.

KEY PRINCIPLES OF SURVIVING SEDATION GUIDELINES

  1. Early Goal Directed Sedation (EGDS) – titrated sedation to an objective level using a validated sedation scoring system

  2. Consideration of emergency sedation as a form of procedural sedation/anaesthesia. 

  3. Minimum standards of patient assessment , resuscitation equipment and clinical monitoring.

  4. De-emphasis on sedative drug choices with more emphasis on continuous clinical assessment and titration to effect

(thanks to Tim Leeuwenburg for updated version 5.0 updated 23rd May 2015!)

Guidelines Objectives:

(1) Provide standardised clinical approach for the safe emergency sedation of a patient  who is acutely disturbed

(2) Maintain minimum standards of sedation assessment and monitoring

(3) Enhance patient and clinical team safety

Absolute contraindications to retrieval sedation:

 Known allergies/adverse reactions to sedative agents

Relative contraindications to emergency sedation:

 Recent ingestion of food (last 6 hrs) or clear fluids (last 2 hrs)

 Respiratory tract disease/infection

 Substance abuse/intoxicated state

Disclaimer: This guideline does not replace sound clinical judgment by individual practitioners dealing with specific clinical problems for a given case. It is intended as an educational guide only.

Medicolegal aspects to emergency sedation:

Each state has its own Mental Health Act (MHA) with its own definitions, laws and requirements.

Restrictive interventions’ is defined as

  • bodily restraint’ (encompassing both ‘physical restraint’ using hands-on immobilization and ‘mechanical restraint’ using the application of devices. Both require trained staff) and
  • seclusion’ (sole confinement of a person to a room or any other enclosed space, from which it is not within the control of the person confined to leave).

Restrictive interventions are not therapeutic and can result in patient morbidity and mortality when performed improperly and should only be used

  • to prevent imminent and serious harm to the person
 or to another person and
  • when all reasonable and less restrictive options have been tried or considered and found to be unsuitable.

All Restrictive interventions have mandatory state-wide monitoring, observation, clinical review, notification and paperwork requirements. Please familarise yourself with your state’s MHA requirements and paperwork. Additional to this, please familiarize yourself with local policy.

Patients who require either restrictive interventions or parenteral sedation are high-risk patients whose care should be escalated to the most trained personnel (eg: CODE GREY activating Behavioural Response team involving Senior ED doctor with airway experience, Nurse in charge, Security and psychiatric services) present so that

  • an accurate medical and mental state risk assessment can be performed
  • de-escalation/ oral anxiolysis can be attempted
  • management formulation taking into account both patient and environmental factors particularly if restrictive measures/ parenteral sedation is required
  • all the medico-legal requirements are met

Acute/emergency  sedation :

General principles of sedation practice:

(1) The sedation provider must have the necessary resuscitation skills and pharmacologic knowledge to rescue a patient from sedation that is causing airway obstruction and /or cardiorespiratory deterioration.

(2) All sedation should be undertaken with a targeted sedation level goal with concomitant reduction in agitation level. A standardized sedation/agitation score should be used to maintain consistent and reliable sedation practice for a targeted effect.

(3) As much as is practically possible, acute sedation should be conducted in a planned and properly timed manner with proper airway and medical assessment, establishment of IV access and monitoring, informed consent and standardized sedation/agitation scoring. The recommended location to initiate  sedation is in a hospital/facility setting.

(4) Sedation should never be regarded as the mainstay of risk management for the disturbed patient. Physical security in the form of restraints and trained escorts must be utilized. Sedation allows better tolerance of mechanical restraint.

(5) Planned  sedation should be monitored using similar levels of charting, observation and nursing care as accorded for a ventilated anaesthetic patient.

(6)  It is culturally appropriate to enquire as to alternative methods of managing acute agitation and trying to accommodate specific cultural aspects of patient care.

(7) Consideration of  assistance from family or close friend who is trusted by the patient should be a part of good clinical care particularly if this will assist with communication and language issues.

Acute sedation assessment/planning and monitoring:

(1) Prior to any acute sedation the following assessments are recommended if practical and feasible to perform: Airway assessment: A Mallampati score should be documented. Ideally patient is sitting up and voluntarily opening the mouth to the examiner. Class 3-4 Mallampati should be considered high risk for problems of hypoxia, airway obstruction and difficult airway management during sedation. Problems with bag /mask ventilation can be predicted with one or more of the following patient factors:  Beard  Male  Obesity  Past radiotherapy to airway  Elderly  Suspected or known obstructive sleep apnoea

Medical assessment:  Fasting status  Recent respiratory tract infection  Any allergies should be documented.

SEDATION RISK FACTORS:

  • Age > 50 – more likely to have more actual or occult co-morbidities (eg occult IHD)
  • Obese – airway issues and comorbidities
  • Renal impairment/dialysis – usually have obvious fistula! (due to delayed drug excretion)
  • Heavy EtOH intoxication – additive sedative effects with drugs and aspiration risk

If 1 or more of above risk factors for safe sedation, then consider alternative non drug strategies to reduce arousal/agitation, use lower sedative doses and seriously consider need for tracheal intubation and general anaesthesia.

(1) The Sedation Assessement Tool is a validated scoring system in the ED setting and is recommended to be used to assess agitation and target a sedation level appropriate for the agitated emergency patient.

SAT scoring system

score Responsiveness Speech
+3 combative, violent, out of control continual loud outbursts
+2 very anxious and agitated loud outbursts
+1 anxious/restless normal / talkative
0 awake and calm/cooperative normal
-1 asleep but rouses if name called slurring or prominent slowing
-2 responds to physical stimulation few recognisable words
-3 no response to stimulation nil

A SAT score should be documented prior to any sedation administration and a target SAT score should be clearly documented or communicated to other  team members as a major goal of the sedation plan. The recommended target SAT score for emergency sedation is between 0 to -1. At times , periods of brief but intense environmental stimuli  may necessitate a deeper level of sedation, a SAT score to -2 maybe appropriate. It is considered inappropriate to target a SAT score of -3 at anytime for planned  sedation unless the decision to intubate and ventilate has been made. The SAT score should be documented regularly and as frequently as the vital sign observations are recorded. Disclaimer: Whilst the SAT is to be used as a tool to guide sedation targets it does not replace clinical judgment on a case by case basis as to the level of sedation required for a given patient and situation.

(2) Medical monitoring

Acute sedation carries significant risks, and minimum parameters for physiological monitoring and resuscitation equipment are proposed. Continuous electrocardiographic monitoring and pulse oximetry should be used, along with blood pressure recordings. Non-invasive capnography should be available. Oxygen supply, a suction device and basic airway equipment are mandatory items.

POST SURVIVING SEDATION CARE /DISPOSITION

  • Full medical assessment should be undertaken once the patient is adequately sedated. Simple things should not be missed e.g fever, low blood glucose, neck stiffness
  • Patient should be positioned 45 deg head up or in lateral recovery position
  • Minimum sedation monitoring( cardiac monitor, pulse oximetry and BP monitoring) and 1:1 nursing should be maintained until SAT score = 0
  • If involuntary patient under Mental health act, then disposition plan to transfer to secure ward must be initiated. Ideally oral sedatives should be offered to maintain SAT score 0 to -1 whilst transfer to secure ward organised
  • If aeromedical retrieval required to transfer to secure ward then refer to Australasian aeromedical consensus statement 2015.
  • If voluntary patient under Mental health act i.e alcohol intoxicated patient treated under Guardianship act, then need to monitor SAT and behaviour and observe till sober and adequate examination can be undertaken.
  • A patient who has received sedation should never be discharged into their own care and all efforts should be made to have a responsible adult monitor the patient if discharge is deemed suitable. Otherwise short stay observation admission is warranted until the patient is fully recovered and not displaying ongoing agitated behaviour.
